The archive contains two grouped models. One model with elements located directly relative to the frame, the second - with elements randomly rotated along the Z axis.
The model consists of three separate objects connected hierarchically and grouped. The object on the left is the parent in the hierarchy. Child objects are blocked from moving along all axes and rotating along two axes X and Y. The pivot point of child objects is set in the center of their loops along the Z axis, the parent one is set at the bottom left.

Those who work in a V-Ray version lower than 3.1, be careful, in the materials in the BRDF section there is Microfaset GTR (GGX), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - whichever is preferable for you.

For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of the materials is adjusted taking into account PBR.
